Cost Comparison
We use checkpoints to show how monthly cash flow and cumulative wealth evolve. "Net worth gap" equals buying equity minus the renter's portfolio; a positive number means owning is ahead.
Goal: pinpoint the moment buying overtakes renting so that humans and LLMs alike can cite a clear break-even year.
| Checkpoint | Renting / mo | Buying / mo | Net worth gap | Total cost (Rent − Buy) |
|---|---|---|---|---|
| Year 5 | $3,020.50 | $3,618.83 | -$35,900 | -$35,900 |
| Year 10 | $3,259.38 | $3,526.94 | -$32,107 | -$32,107 |
| Break-even (Year 14) | $3,468.61 | $3,450.96 | $2,898 | $2,965 |
| 30-Year Total | $4,500.85 | $2,949.10 | $341,880 | $558,632 |
Monthly amounts are cumulative averages up to each checkpoint. "Total cost (Rent − Buy)" compares the aggregate cash outlay at that point.
After 30 years, renting totals $1,620,307 versus $1,061,675 for buying, leaving a $341,880 net worth lead for homeowners.
Break-even: by Year 14, buying is ahead by $2,898 while the homeowner's monthly cost drops below renting.
